NGK Ignition Coil Boot - Infiniti FX45 2003-2008

This is an NGK coil-on-plug boot for the 03-08 Infiniti FX45 — the silicone boot that bridges the ignition coil and spark plug. It's built to OEM tolerances from premium silicone and includes the internal spring and ferrite resistor for a proper connection and RFI noise suppression. NGK recommends replacing COP boots whenever you change spark plugs to prevent misfires from a cracked or hardened boot.
